I invite you to check out a special Memorial Day Blawg Review #110 from Norman Gregory Fernandez of Biker Law Blog.  Fernandez describes Memorial Day this way:

You see Memorial Day is a day that is set aside each year to honor those men and women who have lost their lives in the Service of the United States of America.

To honor these men and women is to honor not only the United States of America, but to honor the freedom for which the United States of America stands.

Above all, Memorial Day is a day is to remember those brave souls whose willing self sacrifice has given us all a chance to live free in the greatest nation on earth. God bless those men and women who have died in the service of the Untied States of America.

It is hard to say it any better than that.
